Examples: Input : s = "GeeksforGeeks" d = 2 Output : Left Rotation : "eksforGeeksGe" Right Rotation : "ksGeeksforGee" Input : s = "qwertyu" d = 2 Output : Left rotation : "ertyuqw" Right rotation : "yuqwert" Method 1: We have existing solution for this problem please refer Left Rotation and Right Rotation of a String link. We will solve this problem quickly in python using String Slicing. Approach is very simple,
Implementation: Python3
Output: Left Rotation : eksforGeeksGe Right Rotation : ksGeeksforGee Method 2: We use extended string to rotate the string. We will solve this problem quickly in python by slicing extended string. Approach is very simple, Use extended string Extend_str, for Left rotation
Lfirst = Extended_str[n : l1+n] . For Right rotation Rfirst = str[l1-n : l2-n]. Implementation: Python3
Output Left Rotation : ksGeeksforGee Right Rotation : ksGeeksforGee A string is given, our task is to slicing the string into two way. One is clockwise and another anticlockwise. 1. Left (Or anticlockwise) rotate the given string by d elements (where d <= n). 2. Right (Or clockwise) rotate the given string by d elements (where d <= n). ExampleInput: string = "pythonprogram" d = 2 Output: Left Rotation: thonprogrampy Right Rotation: ampythonprogr AlgorithmStep 1: Enter string. Step 2: Separate string in two parts first & second, for Left rotation Lfirst = str[0 : d] and Lsecond = str[d :]. For Right rotation Rfirst = str[0 : len(str)-d] and Rsecond = str[len(str)-d : ]. Step 3: Now concatenate these two parts second + first accordingly. Example Codedef rotate(input,d): # Slice string in two parts for left and right Lfirst = input[0 : d] Lsecond = input[d :] Rfirst = input[0 : len(input)-d] Rsecond = input[len(input)-d : ] print ("Left Rotation : ", (Lsecond + Lfirst) ) print ("Right Rotation : ", (Rsecond + Rfirst) ) # Driver program if __name__ == "__main__": str = input("Enter String ::>") d=2 rotate(str,d) OutputEnter String ::> pythonprogram Left Rotation: thonprogrampy Right Rotation: ampythonprogr

How do you rotate a word in Python?Step 1: Enter string. Step 2: Separate string in two parts first & second, for Left rotation Lfirst = str[0 : d] and Lsecond = str[d :]. For Right rotation Rfirst = str[0 : len(str)-d] and Rsecond = str[len(str)-d : ]. Step 3: Now concatenate these two parts second + first accordingly.
How do you rotate words in a string?Method#1: A Simple Solution is to use a temporary string to do rotations. For left rotation, first, copy last n-d characters, then copy first d characters in order to the temporary string. For right rotation, first, copy last d characters, then copy n-d characters.
How do you create a rotating list in Python?Let's discuss different ways we can rotate a list in Python.. Method 1: Rotate a list using Slicing.. Method 2: Rotate a list using list Comprehension.. Method 3: Rotate a list using collections. deque. rotate(). How do you shift a circular string in Python?Given a string of size n, write functions to perform following operations on string. Left (Or anticlockwise) rotate the given string by d elements (where d <= n). Right (Or clockwise) rotate the given string by d elements (where d <= n).
